MACHINE FOR SPLITTING THE TANGS AND FORMING THE SOCKETS F SHOVEL-BLANKS.

SPECIFICATION forming part of Letters Patent No. 348,037, dated August24, 1886.

Application filed March 2T, 1885.

, and exact description of `the invention, such as will enable othersskilled in the art to which it appertains to make and use the same.

My invention relates to an improvement in machines for splitting thetang for the handlestraps and forming the socket in blanks for makingshovels. spades, and scoops; and it consists in the combination of ablank-holder having a movable j aw, tang-supporters,cutter, andoperating` mechanism, as will hereinafter more fully and at largeappear.

To enable others skilled in the art with which my invention is mostnearly connected to make and use it, I will proceed to describe itsconstruction and operation.

In tlie accompanying drawings, which form part of this specication,Figure lis a front elevation of my improvement in machines for splittingthe tang and forming the socket in blanks for making shovels, spades,and scoops. Fig. 2 is a side elevation of the same. Figs. 3, 4, 5, 6,and 7 are detail views.

Reference being had to the accompanying drawings, A represents theordinary punching-n'lachinc having what is known as a stopmotion, inwhich machine, in place of the punch, I insert a cutter, such as shownat B in Fig. l, the construction of which is clearly shown in Fig. 6.

To the saddle C of the machine I attach a fixed jaw, D, and a movablejaw, E, which is operated through the medium of a wedge, F, and spiralsprings G. rIhe extent of the outward movement of the jaw E is regulatedthrough the medium of a set-screw, H. The wedge F is attached to themovable head I of the machine. The office of the wedge is to close thejaw E against the blank, and that of the springs G to retract the jaw Eas the wedge F is drawn up by the movable head I. In recesses in thejaws D E are arranged tangsupporters J, which move down in the jaws andthrough the saddle C,by the lower part of Serial No. 160,241. (Nomodel.)

the movable head acting upon their upper ends, and as the head is drawnback the spring K, acting upon the plate or follower T, forces thetang-supporters up into about the position shown in Fig. l, and alsocauses the rod P to force up from between the jaws the blank O. To themovable head I is attached ahammer, L, and a part of the upper face ofthe jaw D serves as an anvil, M, and a recess, N, is formed in said jawfor the reception of the blank O. The saddle C is held :in position onthe machine through the medium of setscrews Q.

By reference to the accompanying drawings and fromthe foregoingdescription the skillful mechanic will be enabled. to construct myimprovement. Therefore I will proceed to describe its operation, whichis as follows: The machine being put in operation in the usual manner ofthe punching-machine having a stop-motion, the operator places theblanksuch as shown in Fig. 7 between the jaws D E. The head I in itsdescending motion first causes the wedge F to move forward the j aw E,so as to clamp the blank O firmly against the stationary jaw D, at whichpoint the cutter B commences its work of splitting the tang B of theblank O, and as the 'cutter enters the tang, splitting it, thetang-supporters .I are moved down at the same rate of speed that thecutter splits the tang, thereby causing the cutter to split the tangevenly-that is to say, that that part of the tang-supporters marked Sfirmly braces each side of the tang R of the blank O, moving downward alittle in advance of the downward movement of the cutter, therebypreventing the heated metal from having any lateral movement that wouldtend to produce unevenness in the splitting of the tang. The cutter B,after splitting the tang, enters the blank O sufficiently to form thenecessary socket'therein for thc reception of the lower end of thewooden handle in the shovel-blade when said blank is rolled-out forforming said blade. The cutter having split the tang R and formed saidsocket, at this point the movable head I commences moving upward, whichwill withdraw the wedge F and cutter B, and as said wedge is beingwithdrawn the springs G move back the jaw E, and the spring K moves upthe tang-supporters J, and the rod P forces the blank O IOO from betweenthe jaws D E. Ther operator then removes the blank through the medium ofa pair of tongs (not shown) or other suitable device, and places it inthe recess Nin jaw D, and then places a fresh blank between the jaws DE, at which time he places the split tang of the blank O upon the anvilM, and thc downward movement of the hammer L will close the split tang;but prior to the closing of the said tang a little cinder should beplaced between the split parts of the tang and in the socket to preventwelding in the rolling process, and thus the operation is re peated forthe splitting and closing of the tang of each blank, as above set forth.

Having thus described my improvement, what I claim as of my inventionis- 1. In a machine forsplitting shovel-blanks, a cutter for splittingthe tang, in combination with reciprocating jaws for supporting the tanglaterally while being split, substantially as described.

2. In a machine for splitting shovel-blanks, a reciprocating head and acutter secured thereto, in combination with jaws for supporting the tanglaterally, said jaws being moved by said head in unison with the cutteras it advances into the tang, substantially as described.

3. In a machine for splitting shovel-blanks, a reciprocating head and acutter secured thereto, in combination with reciprocating tangsupportingjaws and a yielding follower for holding the jaws and head lin operativerelation to each other, substantially as described.

4. In a machine for split-ting shovel-blanks, a reciprocating cutter, incombination with jaws for supporting the talig laterally andclamping-jaws for holding the blank while being split, substantially asdescribed.

5. In a machine for splitting shovel-blanks, a reciprocating cutter, incombination with reciprocating jaws for supporting the tang laterallyand a fixed and a movable jaw for holding the blank while being split,snbstantially as described.

6. In a machine for splitting shovel-blanks, a reciprocating head, acutter, and a wedge se cured thereto, in combination with tang-supporters, clampingjaws operated in one direcscri bed.

tion by said wedge, and springs for separating them, substantially asdescribed.

7. In a machine for splitting shovel-blanks, a reciprocating cutter forsplitting the tang, in combination with jaws for supporting the tanglaterally while being split, clampingjaws for holding the blank, and arod for raising the blank after it has been split, substantially asdescribed. l

8. In a machine for splitting shovel-blanks, a reciprocating cutter, incombination with reciprocating tang-supporting jaws, clampingjaws tohold the blank, a yielding follower supporting the firstnamed jaws, arod, and a spring for operating said follower and rod, substantially asdescribed.

9. In a machine for splitting shovel-blanks, a reciprocating head havinga hammer at tached thereto and carrying a cutter, in *combination withblank-clamping jaws, one of which has an anvil formed thereon in Suchrelation to the hammer on the head that .the split tang of one blank maybe closed by the same stroke of the head that is splitting an otherblank, substantially as described. l

10. In a machine for splitting shovel-blanks, a reciprocating headhaving la cutter secured thereto, in combination with blank-clamping ijaws, reciprocating tang-supporting jaws operated in one direction bysaid head, and a spring for returning them to their normal position,substantially as described.

l1. In a machine for splitting blanks, a detachable saddle provided witha pair of vertically-reciprocating jaws, a fixed jaw, ahorizontally-adjustable jaw, and springs for operating the latterjaw inone direction, substantially as described.

12. In a machine for splitting shovel-blanks, a reciprocating headhaving a cutter and a wedge attached thereto, in combination with a pairof reciprocating tang-supportingjaws, a fixed and a movableblank-clamping jaw, springs for retracting said movable jaw, and aspring actuated follower for raising the tang-supporting jaws,substantially as de- HENRY M.
